The device may be arrangedand adapted for attachment to" a carriage ortractor of any desirable typefbut forithe purpose of illustration i.-isshown in connection with a'tractor likcitliat set forth in an splicetionfiledby me on april 1,' 1912,: Se'r1al No;

5 whereby the machine may be steered and turned. The specificconstruction and arrangement of the tractor by itself forms no part ofthe present invention and no further descriptionthereof will be given inthe present application except as to such parts that are necessary tothe -full'understanding of the invention or enter. into the combinationsof the claims.

The implement carrier or dragframe is shown attached tothe tractorthrough the medium of a hinged parallelogram frame which cooperates withthe adjusting and raising and lowering device as fully set forth in a'companion application Serial- No. a 7 04,036'filed herewith for atilling machine. ,The tractor is provided at itsrear 3 53. with brackets6 near the top and bOtte-Yi of the pedestal side frames 2.- Thesebrackets 6 are provided with bearings whose axes are in the samevertical plane, The upper and lower'member's 7 of the parallelogramframe are hinged at one end tothese brackets 6 and at their outer endsto the vertical frame .members 8, the vertical distance between the. 30

centers of the axes of the inner and outer pivots'being the same. Theadjusting and raising aflid lowering device includes a yoke 9 pivoted atits'inner end about 'the'iaxis of the upper brackets 6 and haying,a'swivel block 10 atits outer .end. A nut '11 is rotatably mounted inthe swivel block 10 andhas a screw .12 workin therethrough .whose lowerend is hinged about the axis of the pivota8 which connects the upperparallelogram frame members '1. and-the vertical members 8tl1ereof. Thenut 11 is provided with a handw'heel 13 for rotating it. n

A rod 14 is pivoted at one end to the yoke mb 9 and its opposite endportion is telescoped within,a hollow screw 15. The rod 14 is providedwith a longitudinal slot 16 through which a pin'flZ on tliehollowscrew'15 projects, sothat tho-rod and-Ware permitted 1 independentendwise movement but are pre 'nut 19 which is swiveled in a swivelsupport 20 having trunnions 21 journaled in 9.1::

ings 22 on the carriage frame 1. *Thenut 19 may be rotated through themedium of any suitable driving mechanism which may obviously derive itspower from the motor.

which propels the tractor or any other source of power speciallyprovided.

An operating lever 23 is connected to a clutch mechanism so that whenthe lever is moved'in one direction the nut 19 is rotated to move thescrew and rod lengthwise in the proper direction to raise theparallelogramframe with the implement carrier or drag thereon, and whenthe lever is moved in the opposite direction the screw and rod, aremoved reversely tolower the parallelogram frame and implement holder.This mecha nism is shown and described in detail in the said otherapplication Serial No. 704,036 filed herewith. Hence, no further description is necessary in .the present application.

The drag as shown comprises an expansible and contractible frame hingedat one sideto the parallelogram frame. This drag frame has side memberscomposed of pairs of spaced channels 24 placed with their webs vertical.The side members are hinged at one end on the lower cross bar 8" of theparallelogram frame and their outer end portions are connected by across bar 25. Yokes 26 are hinged to the cross ar 25 at one end and areprovided at their opposite ends with cross members 27 having openingstherethrough. Bolts 28 are hinged at one end on the upper cross bar 8'of the parallelogram frame and are slidably fitted in the openin s inthe cross members 27. Portions of t e bolts 28 are screw-threaded to fitnuts 29 swiveled in cross supports 30 on the yokes 26 at about themiddle thereof. By turning the nuts the bolts are moved lengthwise ineither direction, thereby tilting the implement holder frame withrespect to the par allelogram frame. I

Pivotally mounted on bearings 31 secured to the bottoms of the channelside members 24 of the implement holder frame are'yokes 82 havingtoothed sectors 33 extending up between the channels. The teeth of thesesectors are engaged by worm screws 34 jour-- naled in brackets 35 on thetop ofsaid channel side members 24. The end portions of these wormscrews are pijovided with olyg mar faces 36 to be engaged by a suita lewrmu for turning the worm screws. By manipulating the worm screws theyokes are rocked upon their pivots in eitherdirection and are held atanydesirable angle by said worm screws.

Transverse channel members 3'7 are arranged in pairs with their websvertical and" flanges outward. These members are riveted Ola-counterpartbracket extensions 38 of said yokes 32; and riveted to the middleportions of the respective pairs of channels are strut members orcastings 39 having end portions which are counterparts of the channelmemhere so as to provide seats therefor. These members constituteimplement holder beams. Slidably fitted over the channel members 37 arechannel members 40. The flanges of the channel members .37 and 40 areprovided with a multiplicity of perforations 41 adapted to register andreceive locking pins heremafter specified. The perforations 41 arearranged in like series on each side of the longitudinal center ofthefdrag-frame. The

channel members 37 and 40 have their flanges extended laterally, theformer at their outer ends and the latter at their inner ends, andriveted thereto are. oppositely disposed substantially U-shape clips 42in which rightand left hand doublescrews 43 are swiveled. Th'e screwshave collars 4 located between the clips provided with polygonal facesfor the reception of a wrench. Locking members 45 have shank portions45' threaded on the screws 43. They also have pins 46 adapted to'enterthe registered perforations 41 in the flanges of the channel members.Portions of tlie shanks 45 are made square so as to work in squarenotches in the flanges of the channel members in order to hold them fromturning; while inwardly from said square portions they are rounded inorder to permit them. to turn after the square portions are moved clearof said notches. By rotating the screws the.

locking members are drawn toward each,

other to bring the projections 46 into the perforations 41 and therebylock the sliding channel members with respect to the fixed ones. Thesliding channel members 40 are connected at their outer ends by crossbars 47 having end plates 48 riveted to the webportions of said members.The implement carrier or drag thus comprises a rigid frame havingextensible transverse members on which individual holdersfor theimplements to be presently described are adj ustably and interchangeablymounted.

he middle strut member 39 is provided Wlth a central vertical opening 49through which the shank of an implement may be passed. This-opening 49is preferably made to correspond with the contour of a shank 50 havin'flattened opposite faces whereby the shan is permitted endwise movementbut prevented from rotating therein. The striit'member is provided witha circular re cess 51 having tapered side-walls adapted to receive a nut52 having a beveled flanged 'end portion-which is a counterpart of therecessed portion of the strut. A securing plate 53 having a centralopening in which the circular middle portion of the nut fits is securedon top of the strut to hold the nutsides whichare counterparts of thechannel members are adapted to be detachably secured to the slidablechannel members 40.

These holders are provided with pivoted dogs 56 havingpins orprojections 57 adaptedto enter the perforations 41 in the chan-- nelmembers to hold the implement holder in place. These dogs-are providedwith screws 58 adapted to bear-against the to of the holder so that saiddogs'niay 'be eld with their pins 57 in the respective perforations ofthe channel members. These mem- 'Bers'55 have rockin members 59 swiveledtherein, the axis of t e trunnio'ns59 of said rocking members being atright angles to the channel members 37 and 40. The rocking member isprovided with a sector 60 adapted 'to cooperate with a'worm screw 61journaled in. brackets 62 on the member 55. This worm screw 61 isprovided with polygonal faces 63 for .the reception of a wrench.

Swiveled vertically in the rocking member 59 is a shank holder 64: avingan openshank 50 of the implement.

ing therethrough whose si are flattened to correspond with the flattenedsides of the The shank holder is provided with a beveled seat adapted toreceive the counterpart end portion of a nut 65. The nut 65 is held inplace by a plate (36 havinga central opening inwhich the middle portionof the nut is rotatably fitted. The upper portion 67 of the nut isprovided with polygonal faces forthe -reception of a wrench. 'Therocking memberis provided with'a pair of half journal brackets 68 withwhich' similar brackets 69 on the plate 66 cooperate. these hearings isa worm screw 70 which neshes with a worm wheel 71 on the swiveled shankholder 64 whereby the latter may be rotated. This worm screw 70 is also"pro\'.ided with polygonal faces to 'receii e. a

or contra :ted to different widths. The im-.

ple'men' holders with the. eiiception of the i on anounted on the middlestrut member may also be placedat any desirable position Journaled inplement'holder at the middle ofthe frame is,

however, capable of vertical adjustment.

This adjustment is all that is necessary-as the middle implement alwaystravels along the middle of a furrow in a neutral position.

It is different, however, with res ectto the other implements on eithersi e of the middle one, as they have to be set at various angles inorder to throw the dirt toward or away from the middle of the furrow,depending upon the nature of treatment.

- Various combinations may be arranged by adjusting the implementholders. For example, in barring-off a plow may be mounted at either endof the holder frame so that the soil is only. treated adjacent to theplants at the tops of the furrows without touching the middles. Inanother case a double mold board low may be mounted at the middle of therame and on either side thereof maybe arranged right and left hand plowsfor throwing a little 'dirt to the plants on opposite sides of thefurrow, and at the same time stirring'the soil to kill the grass andweeds. Then, again, the soil may be. stirred with shovel blades whichmay be arranged transversely to the direction of travel, in which casethey do not throw earth to the plant, nor from it. Obviously, however,the shovels may be set so that the soil can be thrown toward or from the(plant as desired. Also, in laying-by, the irt may be started at themiddle of the furrow with a double mold board'plow, then throwing it.closer to the plantsby right and left hand mold board plows, and,finally, throwing the soil into the plant with sets of disks. So, too,the entire furrow may be cultivated with disks. There may be a set ofdisks arranged to throw the dirt away from the plant at the top of thefurrow, followed by a set of disks throwing the dirt from the middletoward the plants and these followed -by. other sets of disks ,pickingup the dirt and throwing it still nearer the plants, and, finally, setsof disks throwing the dirt into the plants These and any other desirablecombinations may be effected owing to-the universal adjustment of thedevice.

The device-is adapted-for straddle row cultivation; and by mounting theholders on a tractor of the character-set; forth in said' application,Serial No. 687,929, filed April 1,:

1912, two'entire furrows mayfbe coveredat the same time. v y

In order to facilitate setting the several tiltable and rotatablemembers oft-he chine accurately at the desired angle or 'position,graduated scales and'cotiperating'indicators' may be provided; atconvenient places. For example, asshownin 1,19- and -3, the bolts 28 maybe provided witlra e rnerr graduated lines 28 in the regioli. of

the respective cross members '27 of the yokes 26, so as to coiiperatewitheither the upper or under sides of the members'27, as preferred.Preferably, .the graduations are marked with suitable numbers ranging upand down from the middle or neutral linemarked zero and being coincidentwith theside of the cross member 27 when the carrier frame ishorizontal. Thus, it is easy to set the frame at the desired inclinationup.

or down from its pivot end. The toothed sectors 33 on which the channelmembers 37 are mounted, are provided with semi-circularscales 33' so asto be read in conjunction with marks 33 provided on the top flanges ofthe side channel members 24 of the carrier framefio indicate the angleof the trans verse channel members with respect to the side members. Asdescribed, the perforations" .41 in the members 37 and 40 are air-cvranged in-the same spaced relation-on each', side of the longitudinalcenter of thecarrier.

' tween said pairs of beams, said implement frame, and these lines ofperforations may be used as scales. *Bythis constructionthe extensionmembers'and the various imple-' ment holders may be placed symmetricallyabout the line of draft of the carrier frame, and when the adjustmentsof the implements are changed, by use of these perforations as 3 scales,the various implements may-be placed So that their resultant totalresistance will coincide with the' line of draft of the frame.

The rocking members 59 also are provided with arcuate scales 59 on'theirside faces in 135 coiiperative relation to indicator marks 59" on theadjacent top face of the implement holder frame while the rotatory shankholder 64. has about its upper peripheral portion, preferably on theupper ends of'the 40 teeth of the wormgear 71, a series of graduati'ons64 which may be arranged in two series on opposite sides, or,obv1ously,as a continuous. annular series entlrely girdlmg the member. Thesegraduations '64 are- Pi used in connection with indicator marks 64 onthe plate 66 which holds the nut and shank holder 64 on therockingmember 59.

Obviously, the device admits of considerable modification withoutdeparting from.
